CONVEYER BELT Filed Aug. 8, 1933 2 Sheets-Sheet 2 Inventor f1 llorneyPatented June 12, 1934 UNITED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in conveyerbelts, and more particularly to a novel spike mount for conveyer ordistributor belts.

The principal object of the present invention is to provide a spikemount for conveyer belts wherein a whole group of spikes can be appliedas a unit to the belt, thus reducing labor and expense in equipping thebelt with spikes.

Another important object of the invention is to provide a spike which isof elongated construction in cross section at its base portion in adirection consistent with the direction of force to be applied againstthe same.

During the course of the following specification and claim, otherimportant objects and advantages of the invention will become apparentto the reader.

In the drawings:-

Figure 1 represents a side elevational view of a belt equipped with apair of the units, each of which composes the present invention.

Figure 2 represents a side elevational view of one or" the spikeassemblies secured to a belt.

Figure 3 represents a top plan View of one of the spike assemblies.

Figure 4 represents a sectional view taken substantially on line 4-4 ofFigure 3.

Figure 5 represents a longitudinal sectional view through a slightlymodified form of the present invention.

Figure 6 represents an enlarged fragmentary top plan view showing one ofthe spike elements.

Figure 7 represents a, side elevational view of the modified assemblyshown in Figure 5.

Figure 8 represents a top plan View of the modified assembly shown inFigure 7.

Figure 9 represents a fragmentary top plan enlarged view of the modifiedassembly, showing one of the spikes.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 1 that numeral 5 represents the conveyer belt andthat numeral 6 generally refers to spike assemblies, each of whichdiscloses the present invention.

Figure 2 shows that the assembly consists of an elongated base plate 7secured to the belt 5 0 by bolts 8 and nuts 9.

Projecting upwardly from this plate 7 are the spikes l0 equally spacedapart and each being of substantially ovate shape in cross sectionthroughout its entire length and being tapered from its base endoutwardly toward its free end.

Figures 5, '7, 8 and 9 disclose a slightly modified form of theinvention wherein the base plate 7 is provided with outwardly extendingspike elements 10.

The base plate 7 is provided with openings to accommodate the bolts 8and as is clearly shown in Figures 7, 8 and 9, each spike element 10 isof substantially ovate shape in cross section for about one-half of itslength, starting from its base end, inwardly and from its midway pointoutwardly to its free end, the spike takes on a circular shape in crosssection, although the spike tapers outwardly from the base plate 7gradually toward its free end.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, claimed as new is:

A conveyer belt spike comprising an elongated member having a thick beltattaching end and a relatively thin free end, the said elongated memberbeing substantially ovate in shape at its belt attaching end andgradually tapering to its thin end consistently on the longitudinal axisof the said elongated member, the greatest distance 95 transverselythrough the elongated member being on a line with the travel of thebelt.
